LoadRunner uploading and downloading files

( 1 ) LoadRunner Uploading Files

Web_submit_data ("Importstudent.do",

"Action=https://testserver/console/importstudent.do",

"Method=post",

"Enctype=multipart/form-data",

"Reccontenttype=text/html",

"Referer=https://testserver/console/displaystudentlist.do",

"Snapshot=t12.inf",

"Mode=http",

ItemData,

"Name=uploadfile", "Value=d://excel//data161955.zip", "File=yes", Enditem,

last);

Note: script recording uses the Http/html protocol or the Click and script protocol, which is a script recorded with http/html. It is important to note that regardless of which protocol recording is used, the file path and file name to be uploaded are only English characters and cannot be Chinese characters. Otherwise, the binary stream of the file upload may be recorded in the LR script at the same time.

The problem also shows that LR's support for Chinese is far from enough.

The following is a more detailed example of the application.

Action ()

{

Defines the variable trans_time of type double, which is used to hold the execution time of the transaction.

Double trans_time;

Defines the variable status of type int, which is used to hold the returned value of the transaction execution.

int status;

Lr_start_transaction ("test");

Use the built-in function lr_get_transaction_duration to get the execution time of a transaction.

Trans_time=lr_get_transaction_duration ("test");

status= web_submit_data ("Importstudent.do",

"Action=https://testserver/console/importstudent.do",

"Method=post",

"Enctype=multipart/form-data",

"Reccontenttype=text/html",

"Referer=https://testserver/console/displaystudentlist.do",

"Snapshot=t12.inf",

"Mode=http",

ItemData,

"Name=uploadfile", "Value=e://datafile//data01.zip", "File=yes", Enditem,

last);

Increases the manual transaction, and if the test transaction executes a return value of 0, the transaction executes successfully or the execution fails.

if (status = = 0)

Lr_end_transaction ("Test", Lr_pass);

Else

Lr_end_transaction ("Test", lr_fail);

Print transaction execution time.

if (trans_time)

Lr_output_message ("Transaction Execution Time:%f sec", trans_time);

Else

Lr_output_message ("Transaction Execution time unknown!");

return 0;

}

The following is an example of an application of the Web_submit_data function in the Help documentation for LR, which can be seen in this example.

Web_submit_data ("Attachments",

"Action=http://[email protected]/attachments?" yy=45434 ",

"Method=post",

"Enctype=multipart/form–data",

"Targetframe=",

"Reccontenttype=text/html",

"Referer=http:///[email protected]/compose?" yy=20435 ",

"Snapshot=t5.inf",

"Mode=html",

ItemData,

"Name=userfile0",

"Value=e://sense_sensibility//elinor.txt",

"File=yes",

"Contenttype=text/html",//Override default "Text/plain" for. txt files

Enditem,

"Name=userfile1",

"Value=e://sense_sensibility//marianne.jpg",

"File=yes",

Enditem,

last);

( 2 ) LoadRunner Download File

Action ()

{

/* Download the Help document */

Define an integer variable save the size of the obtained file

int Flen;

Save File handle

Long filedes;

Save file path and filename

Char file[256]= "/0";

Define a random number

char * strnumber;

Returns the string argument after evaluating embedded parameters.

Strnumber=lr_eval_string ("{randomnum}");

Save the path to the file variable

strcat (file, "d://excel//");

Stitching the obtained random number after the file variable

strcat (File,strnumber);

The file suffix name that will be downloaded. rar concatenation after file variable

strcat (file, ". rar");

That's it. A loadrunner has obtained a full file name

To set the maximum length of a parameter, note that the value must be greater than the size of the file

Web_set_max_html_param_len ("20000");

Use the correlation function to get the contents of the downloaded file, where the left and right boundaries are not defined, to get all the contents of the server response

Web_reg_save_param ("Fcontent",

"Lb=",

"Rb=",

"Search=body",

last);

/* Download Help file */

Lr_start_transaction ("Download Help file");

Send a request to download a Help file

Web_url ("Downloadservlet",

"Url=https://testserver3/servlet/downloadservlet?filename=help",

"Resource=1",

"Reccontenttype=application/x-msdownload",

"Referer=",

"Snapshot=t41.inf",

last);

Gets the length of the file in the response

Flen = Web_get_int_property (http_info_download_size);

if (Flen > 0)

{

Open a file in write mode

if (filedes = fopen (file, "wb") = = = NULL)

{

Lr_output_message ("Open file failed!");

return-1;

}

Write file contents

Fwrite (Lr_eval_string ("{fcontent}"), Flen, 1, filedes);

Close File

Fclose (Filedes);

}

Lr_end_transaction ("Download Help file", Lr_auto);

return 0;

}
